-To, all 'whom it may concern.' I

lBe itknown` that I, JOSEPH F. BRIGHT- MAN, a citizen ofthe UnitedStates, and a resident of Syracuse, in the county ot- Onondaga and Stateof New York, have invented a certain new and useful Steam-Trap, lot`which the following is a specification.

This invention has for-its object a steaml trap which isv particularlysimple in construction andhighly efiicient and durable in use inwhich-the container for `the water of condensation is stationary; andthe' inven.

tion consists in the combinations and constructions hereinafter setforth and claimed.

In describing this invention reference is had to the accompanyingdrawimg's` in which like characters designate vcorresponding parts inall the views.

Figure l is a Vertical through the container.

Fig. 2 is a fragmentary sectional view taken on the plane at a rightangle to Fig. 1. Fig. 3 is a sectional View taken online Fig. 4 is adiagrammatic view illustrating the steam trap as connected in a heatingsystem. v This steam trap comprises generally, a

stationary container having an inlet and an outletvalves for controllingthe inlet and the outlet, and means in the container for controlling theoperation of the valves.

1. designates the container which includes a body open at its top and acap 2. secured to-the bodyin any suitable manner as by bolts 3 extendingthrough annular flanges on the body and the cap 2.

4 and 5 designate respectively, the inlet and the outlet for thecontainer, the inlet being located in the cap 2 and the outlet in thebottom of the container, the inlet and outlet 4, 5 being preferablyarranged in alinement.

'6 and 7 are valves for controlling the inlet 4 and outlet respectively,these valves being carried by cages 8 ,`9 threadinglr into the inlet V4and outlet respectiveh. and

. formed with guides 10, 11 in which the stems 12, 13 of the. valvesslide.

14 and A15 are springs located in the inlet 4 and the outlet 5respectively, and arranged to normally hold the valves G and against theseats on the cages 8, 9.

The container is also formed with a pressure equaliai'ng passage'fglnoiially closed by avalve 17 carried byl the ,cage y18 and sectionalview having a stein 19 in the cage, the valve being held in its closedposition by a spring 20 encircling the stem and abutting against theguide 1S and the shoulder 21 on the stein.

The means for controlling the operation of the Valve operates to openthep'outlet valve 7 and the equalizing valve 17 which are nor-4 mally in.their closed positionalternately` with the inlet valve which isnormally in its open position, said mechanism including graduallymovable parts and connectei'es opeigated by said parts to have a'quiiilaction after the gradually moving parts have been actuated apredetermined amount. The

gradually movable parts include a float 22 and connections operated bythe float. These connections comprise a lever 23 pivoted at 24 betweenits ends to a bracket 25 depending from the cap 2, a rod 26 arranged inaxial alineinent with the stems 12, 13 of the 'valvesf 6, 7 a toggle,one link of which is connetted to the rod, the other link of which isconnected to the lever and spring normally tending to break the toggleand resist the nioyteipnentthereof which carries the toggle ioiilforward and into' the dead center line l-ietogglej The rod -26 is guidedin suitable arms 27 carried by the 'bracket 25. The toggle is here shownas double in construetion and includes a double link. 28 pivoted at 29to a block 30 on the lippe@ end of the rod 26. a double link 31 pivotedat 32 to the link 28 and a link b3 pivoted to the link 31 at 34 and toone arm of the lever '23, the other arm of which carries the oat 22.

Said connections further include springs 35 connecting the links 31ofthe toggle. these springs 35 being connected to the.outer ends of thetoggle links and normally -tending to hold the toggle out of its deadcenter line. that is. a line passing through the points a4. 32, se.

The equalizing part is operated by the rod 2Gthrough a lever 37 pivotedbetween its ends at 38 to a bracket 39, one arm of the lever having anadjusting screw 40 coacting with the end of the stem 19 ot the valve 17andthe other arm thereof being pivoted at 41 to a collar 42 fixed to therod-,26.

In operation, the inlet 4 is connected to a pipe :i543 which is thereturn pipe of a heating system including units as radiators 44 and theoutlet 5 is connected b v a pipe 45 to the boiler 46. y

The equalizing passage 16 is connected by a pipe 47 to the upper part orsteam dome f the boiler.

In operation, the outlet valve 9 and the equalizing valve 17 are closedwhile the valve 6 is open.- lVater of condensation or steam flows intothe container, the steam condensing therein, and as the level of thewater rises inthe container, the float 22 is carried upwardly graduallymoving the lever 23, link 33, toggle links 28 and 31 graduallytensioning the springs 35 as they pass into the dead center line fromthe upper side thereof, and as the joint 32 of the toggle passes to theopposite side of the dead center line from thatseen in Fig. l, thesprings complete the opening of the toggley with a quick acticn' forcingthe rod 26 downwardly so that the spring 14 will close the intake valve6 and open the outlet valve 7 against the action of its spring.- Y

This movement also moves the'lever 37 to open the equalizing valve 17 sothat the pressure within the trap is the same as that in the boilerhence permitting the water to flow into the boiler through the outlet 5'and pipe 43.

As the oat falls due to the lowering o f the water. level, the toggle isgradually operated until its Joint 32 again passes the dead' center linewhereupon the valves 7' and '17 are closed and the valve 6 opened with aquick action.

If desired,- a cut-out pipe494 may be prov vided connecting the returnpipe 43 andthe water outlet 45.

The body 1- is provided with' a suitable blowout passage 50.

What' I claim is:

1. In a steam trap, the combinationof a container having alined inletand outlet passages at its upper and. lower ends, valves controllingsaid passages has/ing stems extending toward each other,.actuating meansfor the valves comprisingan axially fmovable rod alined and coactingwith the stems, a support located in.k the container adjacent the rod,and means carried bythe support and within the container for actuatingthe rod, said means comprising a iioat and mechanical connectionsbetween the float and the rod, substantially as and for the purs.,V posedescribed.

-2. In a steam trap, the combination of' a' container having alinedinlet and outlet pas4 sages at' its upper and lower ends, valves forcontrolling the 'passages having stems, actu-` ating means for thevalves Acomprising an axially movable' .rod alined and coacting .withthe stems, toggle means 4having one of its. links pivoted between itsends to the rod, a spring connecting the toggle links, 'a float locatedin the container, a lever carrying the float, and connections betweenthe lever and which is pivoted between its ends to the rod,

means connecting the other arm of the lever andthe other link of thetoggle, a` spring connecting the toggle links and arranged to resistmovement of the toggle -links into a straight line to move the toggle toeffect a quick action of the toggle' when the joint thereof has passedthe dead center line of the toggle, and springs tending to close saidvalves, substantially as and for thepur'- posespeciiied.

4.'
